Alpha is typically used to represent the value added or subtracted by active investment management strategies. It shows how an actively managed investment portfolio performed compared with the expected portfolio returns produced simply by benchmark volatility (beta) and market changes. A positive alpha shows that an investment manager has been able to capture more of the upside movement in the benchmark while softening the downswings. A negative alpha means that the manager's strategies have caught more benchmark downside than upside.

Exchange Traded Funds (ETF) are bought and sold through an exchange trading at market price (not NAV), and are not individually redeemed from the fund. Shares may trade at a premium or discount to their NAV in the secondary market. Brokerage commissions will reduce returns.

You should consider the fund's investment objectives, risks, and charges and expenses carefully before you invest. The fund's prospectus or summary prospectus, which can be obtained at americancentury.com, contains this and other information about the fund, and should be read carefully before investing.

Investment return and principal value of security investments will fluctuate. The value at the time of redemption may be more or less than the original cost. Past performance is no guarantee of future results.

The fund is an actively managed ETF that does not seek to replicate the performance of a specified index.

MID is classified as non-diversified. Because it is non-diversified, it may hold large positions in a small number of securities. To the extent it maintains such positions; a price change in any one of those securities may have a greater impact on the fund's share price than if it were diversified.

The portfolio managers use a variety of analytical research tools and techniques to help them make decisions about buying or holding issuers that meet their investment criteria and selling issuers that do not. In addition to fundamental financial metrics, the portfolio managers may also consider environmental, social, and/or governance (ESG) data to evaluate an issuer's sustainability characteristics. However, the portfolio managers may not consider ESG data with respect to every investment decision and, even when such data is considered, they may conclude that other attributes of an investment outweigh sustainability-related considerations when making decisions. Sustainability-related characteristics may or may not impact the performance of an issuer or the strategy, and the strategy may perform differently if it did not consider ESG data. Issuers with strong sustainability-related characteristics may or may not outperform issuers with weak sustainability-related characteristics. ESG data used by the portfolio managers often lacks standardization, consistency, and transparency, and may not be available, complete, or accurate. Not all American Century investment strategies incorporate ESG data into the process.

Proxy Portfolio Risk: The goal of the Proxy Portfolio is to track closely the daily performance of the Actual Portfolio. The Proxy Portfolio is designed to reflect the economic exposures and the risk characteristics of the Actual Portfolio on any given trading day.

ETFs trading on the basis of a published Proxy Portfolio may exhibit wider premiums and discounts, bid/ask spreads, and tracking error than other ETFs using the same investment strategies that publish their portfolios on a daily basis, especially during periods of market disruption or volatility. Therefore, shares of the fund may cost investors more to trade than shares of a traditional ETF.

Each day the fund calculates the overlap between the holdings of the prior Business Day's Proxy Portfolio compared to the Actual Portfolio (Proxy Overlap) and the difference, in percentage terms, between the Proxy Portfolio per share NAV and that of the Actual Portfolio (Tracking Error).

Although the fund seeks to benefit from keeping its portfolio information secret, market participants may attempt to use the Proxy Portfolio to identify a fund's trading strategy, which if successful, could result in such market participants engaging in certain predatory trading practices that may have the potential to harm the fund and its shareholders.

Premium/Discount Risk: Although the Proxy Portfolio is intended to provide investors with enough information to allow for an effective arbitrage mechanism that will keep the market price of the fund at or close to the underlying net asset value (NAV) per share of the fund, there is a risk (which may increase during periods of market disruption or volatility) that market prices will vary significantly from the underlying NAV of the fund.

Trading Issues Risk: Trading halts may have a greater impact on this fund compared to other ETFs due to the fund's nontransparent structure.

Authorized Participant / Authorized Participant Representative Concentration Risk: Only an authorized participant may engage in creation or redemption transactions directly with the fund. The fund may have a limited number of institutions that act as authorized participants. The fact that the fund is offering a novel and unique structure may affect the number of entities willing to act as Authorized Participants. During times of market stress, Authorized Participants may be more likely to step away from this type of ETF than a traditional ETF.
